        * tree-parloops.c (canonicalize_loop_ivs): Call fold_convert
        when the type precision of the induction variable should be
        larger than the type precision of nit.
        (gen_parallel_loop): Update use of canonicalize_loop_ivs.
        * graphite-clast-to-gimple.c (graphite_loop_normal_form): Same.
        * tree-flow.h (canonicalize_loop_ivs): Update declaration.

        * testsuite/gcc.dg/graphite/pr39335_1.c: New.
